I've done that too. Also nice because they're good to 2ohms a side, so you can string up a handful of monitors if needed. Occasionally we'll have a gig where I use my backup amp and we use the IPR for all PA duties (keeping in mind that it's 15's with horns, etc.). Last night we had powered subs, so that wasn't a problem it was the 15's. I didn't even have it close to opened up and it was crankin' loud.

Well, there is a very good chance I will be acquiring a second Thunderchild 118. If I know Duke's designs, they'll make the biggest, baddest PA ever. Then I can run my three 8 ohm cabs as monitors off the other side.
